Anatomy & Physiology Of Speech Production Flashcards
What are the 6 major system of speech production?
Central Nervous System Auditory System Respiratory System Phonatory System Resonators System Articulately System
What is the cerebrum?
The matter in head that include gyro and sulci
What is the frontal lobe responsible for?
Motor movement, executive functioning, planning and memory
Broca’s Area-speech production
What happens in the parietal lobe?
Where sensory information occurs
What does temporal lobe responsible for?
Hearing
Wernicke’s Area- language comprehension
Occipital lobe responsibility
Vision
People with lesions on the basal ganglia have? (6)
Movement disorders Dyskinesia Hyperkinesis Altered posture Dysarthria Parkinson’s Disease
What does the thalamus do?
Integrates sensory informations and relays it to various parts of cerebral cortex
Cerebellum does what?
Coordinates our movements
What is ataxia?
Caused by damaged by cerebellum. Uncoordinated motor movement, inability to produce rhythmic speech sounds
Define Mystagmus
Caused by damage to cerebellum. Eyes have shifting movements
3 parts of the brain stem
Midbrain, pons, medulla
3 connecting fibers
Projection fibers, association fibers, commissary fibers
What are two parts of the outer ear?
